   6          RSA support. This enables the RSA algorithm used for FIT image
   7          verification in U-Boot.

   9          The Modular Exponentiation algorithm in RSA is implemented using
  10          driver model. So CONFIG_DM needs to be enabled by default for this
  11          library to function.
  12          The signing part is build into mkimage regardless of this
  13          option. The software based modular exponentiation is built into
  14          mkimage irrespective of this option.

  25          Enables driver for modular exponentiation in software. This is a RSA
  26          algorithm used in FIT image verification. It required RSA Key as
  27          input.
